Uddin and Begum attempted to improve on, and modernize, Gilchrist's system in a number of ways. For example, in the Uddin and Begum scheme, Urdu and Hindi characters correspond one-to-one. Also, diacritics indicate vowelphonics, whereas in the Gilchrist system the reader must infer vowel pronunciation from context. To facilitate Urdu-Hindustani romanisation in a much wider range of computer software, Uddin and Begum limited their character set to the common ASCII standard.

Note: In traditional Urdu script these vowels sounds are not represented by any letters of alphabet. They are often omitted or sometimes represented by signs which are added to consonants and are termed "Eara'bs". "Eara'bs" representing short vowels are "zabar", "zaer" and "paesh".
